It was clear from the start that this would be a slower-growth quarter at one of the world's leading iron ore producers. Revenue was up 16% -- normally great for a company this size, but not when you've gotten used to growth in the 30%-50% range.

Profitability also lagged Rio Doce's recent levels. Gross margins fell a bit, hurt by currency moves, and Rio Doce posted growth of about 6% in adjusted operating income and 7% in adjusted EBITDA. Margins and returns are still quite good relative to other mineral and metal companies, though.
